WILLIAM J. HALL, OF NEW YORK, N. Y.

DUNIPING-WAGON.

SPECIFICATION forming part of Letters Patent 120,672,704, dated April 23, 1901.

Application filed August 7, 1900. b'erial No. 26,116. (No model.)

To all whom it may concern.- p

Be it known that I, WILLIAM J. HALL, a citizen of the United States, residing at New York, in the county and State of NewYork, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention relates to dumping wagons or carts; and it has for its objects to simplify according to my invention, the parts being shown in normal'position. Fig. 2 is a central longitudinal section thereof, showing the,

" wagon or cart in dumped position. Fig. 3 is an inverted plan of Fig. 1, the running-gear be-T ing omitted. Fig. 4 is a transverse section, on an enlarged scale, taken near the forward end of the Wagon or cart, apart of the front board being broken away. Fig. 5 is a side detail view of the lever devices for actuating the operating mechanism.

Corresponding reference characters indicate corresponding parts in all figures of the drawings.

Referring to the drawings, l designates the running-gear, which may be of any desired or approved pattern, and upon which is mounted and securely fastened a frame 2, the latter serving as a support for the body portion of the wagonl or cart 3, which may also be of 'any `desired construction.

shaft 8 is also mount-ed a gear-wheel 9a, the teeth of which are engaged by the teeth of a double pawl 10, pivotally secured to a lever 11, the latter being loosely mounted upon the shaft 3, so that by a movement thereof in one direction or the other the shaft 8 will be rotated and through the gear-wheel 7 move the rack, the direction of travel being controlled by the pawl 10, as will be hereinafter described.

12 designates a lever which is pivoted to the lever l1 at 13, the lower bifurcated spring end 14 of said lever 12 being adapted to embrace the double pawl 10, while its upper extremity is adapted to engage recesses in a segment 15 on the lever 11. Thus when the lever 12 is moved upon its pivot to the left, as shown clearlyin Figs. 1 and 4, the left leg of the bifurcated spring end,14 will bear upon that side of the pawl 10 to bring one of its teeth into engagement with the gear-wheel 9, while its other tooth will be released, and vice versa.

16 designates a forked brace-rod which is secured to the rack 4, its arms 17 being secured to a bar 18, arranged transversely of the frame 2, said bar being adapted to travel in guides 19, located one at each side of the frame 2, and having its extremities upltnrned, as at 20, at which point they are pvoted to links 21, which in turn are pivotedl to the sides of the body portion 3 ofthe wagon or cart, as shown clearly in Figs. 1, 2, and Thus when the rack is moved to dump the wagon the body portion 3 will be moved rearwardly through the connections just describ d until the center shall have passed the en rail 2a of the frame 2, when it will cant over, as shown clearly in Fig. 2.

22 designates arms pivotally secured to each side of the frame 2, near the rear end thereof, the outer extremities of which are pivoted to one arm of bell-crank levers 23, which in turn are pivotally secured to the body portion 3 of the wagon or cart. The opposite arms 24 of the bell-crank levers 23 are provided with perforations 25, through which staples or other suitable devices 26 pass, said staples being secured to the tail-board 27, so that when the mechanism is moved to dump the wagon the arms 22 will move the bellcrank levers 23 to automatically raise the tailboard to the position shown in Fig. 2.

In order to lock the tail-board against displacement when the'wagon or cart is in its normal position, l provide a locking device 28 at the rear end of the frame 2, said locking device consisting of a bell-crank lever 29, pivotally supported under the frame 2 in any suitable manner, the outer free end of which is provided with a iinger 30, adapted to engage the tail-board l when the latter closes down upon the body portion 3, as in Figs. 1 and 3. ,The other arm 3l of the bell-crank lever 29 is secured by a chain 32 to a screweye 33 or other suitable fastening device, which is adj ustably held in a bracket 34, secured to the rack 4c. Thus when the rack is moved forward to return the body portion 3 of the wagon to normal position the bellcrank lever 29 through the chain 32 (which quickly becomes taut) will be moved on its pivot so as to bring the finger. 30 thereon up into engagement with the vtail-board,where it will remain until a reverse movement of the rack takes place, when it will again automatically fall by gravity into the position shown in Fig. 2.

35 designates a latch pivotally secured to the forward end of the frame 2, Said latch being provided with a hooked end adapted to engagea strap or projection 36, secured t o and projecting from the body portion 3 of the wagon, by which engagement unnecessary strain is removed from the rack 4:," gear-wheel 7, and their adjuncts previously described, when the wagon is in normal position and the body portion 3is in addition locked against accidental rearward movement.

37 designates fingers or guide-plates secu red to the under side of the body portion 3 and projecting downwardly therefrom, so as to engage the inner surfaces of the side rails of the frame 2, and thus prevent any lateral movement of the body portion while it is being moved on the frame 2, as will be understood.

It will be observed from the foregoing that the construction and arrangement of the several parts are such that they are not liable to be easily gotten out of order and that the operating-levers are so positioned with respect to the d,rivers seat 38 that the driver is enabled to dump the Wagon without the necessity of dismounting therefrom and to again return it to normal position by simply reversing the pawl l0, as previously described.

It will also be observed that when the wagon is in its dumped position, as shown in Fig. 2, the end of the rack 4 will bear against the inner face of the end rail 2l of the frame 2, which will have the effect of relieving the teeth on the rack, the gear 7, and its adjuncts from all strain while in that position.

It will also be observed that by means of -the improved construction and relative arrangement as embodied in my invention as hereinabove described by one operation three movements are simultaneously and automatically effected-to wit, the wagon-body is dumped, the tail-board is unlocked, and the tail-board is raised or opened. Likewise in returning the wagon-body to normal position only one operation is necessary to accomplish simultaneously and automatically the return of the wagon-body, the lowering or closing of the tail-board, and the locking of the tailboard in normal position.

It will be apparent that my invention provides in a simple, inexpensive, and effective manner a dumping-wagon that is particularly well adapted for the purposes intended and one that is strong and durable in every respectand Vthat can be easily and quickly operated.

Manifest modifications may be made such, for instance, as applying the same to a twowheeled cart-and other changes may be readily made. lI therefore reserve the right to make any such changes and alterations as come within the spirit and scope of my invention and the terms of the following claims.
